Blockchain in the Supply Chain – Implementation with industrial shop floor systems blockcentric #3 - codecentric AG Blog

Our article series “blockcentric” discusses Blockchain technology, projects, organization and business concerns. It contains skill and findings from our work but also news from the area.

Blockchain ter the supply chain is covered ter several parts:

Part Two (Supply Chain toneel)

This article (Implementation on the shop floor)

Part Four (Clever Contracts for asset tracking)

Part Five (Deploying Brainy Contracts on the blockchain)

You can find an implementation on our demo webpagina: https://asset-tracker.codecentric.den/

Bringing ownership certificates to life

One of the core ideas wasgoed to augment physic hoewel assets with digital mirror assets. Wij needed to make the assets on the one mitt identifiable (tamper-resistant) and on the other forearm trackable ter the blockchain by setting up digital ownership certificates ter the blockchain.

The core process steps of the initial system are:

  • Generating a unique asset ID which is the verbinding to the ‘mirror asset’
  • Retrieving the asset types, identifying the type of product that wij want to track
  • Applying the asset ID permanently to the asset, by using a trusted device
  • Transferring the ownership certificate of the asset to the manufacturer’s wallet
  • Transferring the ownership certificate to the initial holder te the Asset Management System at the ogenblik of sale

Each step entails, unique challenges, some of which wij will have a closer look at zometeen on. Here you see an overview of the process:

Initial thoughts and architecture

What wij intended te the beginning wasgoed to have a quick proof of concept that is able to translate into a scalable verhoging. Wij have determined to use ethereum since wij would like the system to become a widespread solution. Additionally the maturity spil well spil the capabilities of the ethereum clever contracts seemed to be right for our requests. Furthermore, wij wished to have a haptic case and example and determined to search for industry production systems that wij could use to convert it into trusted devices. After some research and some calls, http://www.couth-butzbach.den/ provided us with a mobile needle marker system that is also used ter mass production processes. A software component will be described ter a separate blog postbode.

The system consists of the industrial marking system that is remote-controlled by our piggy-back device that runs a blockchain knot. The device itself is a Raspberry Pi 3b with a touch display and a lean electron app spil user interface. The communication protocol of the specific industrial marking device is proprietary. On the other forearm, there is the asset management portal which is a web application and DAPP components. Both sides are connected to the blockchain.

Generating a unique asset ID

The commencing point is the interface of the marker and the asset to mark. After booting, the device connects automatically and starts the electron interface.

The technicus confirms the generation of the ID. This can be performed either on the device or ter the blockchain ter order to avoid improbable collision. Te the latter case it is advisable to implement some kleuter of three-phase commit protocol te order to confirm the requested ID after application to the asset.

Retrieving the asset type

After having loaded an ID to apply, the device shows the available assets for this production line. It can be a pre-configured selection, immobilized options or free text.

Applying the asset ID

Now everything is ready to apply the ID either by pushing the create digital asset &, engrave button or by pulling the trigg er of the marker.

The marking process starts and is finished ter seconds (click on the photo to begin the vergif animation)

Different types of markings can be applied by the trusted device: logos, QR codes, gegevens matrices, alpha numeric serial numbers, etc.

Transferring the asset to the manufacturer’s wallet

At this time the asset is booked to the wallet of the manufacturer that is tied to the trusted device of the marker and the asset instantaneously shows up (event based) ter the asset management system.

Sending the asset the the fresh possessor

Now the manufacturer is able to pass on the asset to the fresh possessor by applying his wallet ID or, te a zometeen version, his treat or real name.

It is possible to have different views of the same wallet. Created assets, received assets, asset details.

Practice test of the solution and conclusion

Te summary, the concept does work successfully, but there are still uncertainties. Ter the meantime wij have bot working on enhancing usability and on covering more and more aspects of the utter supply chain verhoging. There are known aspects to work on and adjustments to utter production environments remain to be made. Wij are looking forward to completing our very first practice tests for the solution soon.
